Zealot

I just got this one today. The description doesn't do it justice. It's very cool. You basically paint objects with a rope. Sounds dumb, but it's not. The graphics and sounds are amazing, and the controls are a good blend of touch and accelerometer. Well worth the $5.

Genius

It does! Very well... worth the money, I think. I love it, and my wife loves it even more (she has a notoriously shaky hand)

By the way, my early impressions of Zen Bound: it's very different from any game I've ever played, but it's so well-done you just have to love it. From the rendering to the music (follow the startup suggestion of using headphones. They're not kidding), this game has a high class/$ ratio. The gameplay is intuitive, simple, addicting. It really does start to feel like you're manipulating a real object in your hand.
